LIGHTER FOR BURNERS OF RANGES.

Application filed December 21, 1926. Serial No. 156,159.

This invention relates to certain improvements in lighters for burners of ranges and is a continuation in part of all matter that is common to my pending application Serial No. 114,478, filed June 8, 1926. The primary object of the invention is providing a range with a lighting member extending from a burner in the open part of the range through the oven housing to an oven burner,

whereby the 'oven burner may be lighted from the external or main burner.

A further object of the invention is to provide a range having external burners and an oven burner having communication with the main burner, and a lighter having its outer end adjacent the main burner and its inner end adjacent the oven burner, whereby the latter burner may be lighted from the main burner.

A further object of the present improvement is providing a pipe between the main burner and the oven burner with a lighter that communicates with the pipe between the oven and main burner, whereby the vapor from the main burner enters the lighter and flows therethrough to the oven burner.

A further object of the invention is to provide a range with an oven burner and an external main burner communicating with each other by means of a pipe, and a lighter having an intermediate communication intermediately with the said pipe, whereby vapor flows in both directions, whereby fire flashes along the lighter from the mam burner to the oven burner.

In the accompanying drawings: Figure 1 is a horizontalsection through a range with my improvement applied thereto. Figure 2 is an inverted plan view of the oven burner and main burner, the lighter shown in position for conveying fire from the main burner to the oven burner.

Figure 3 is a vertical sectional view on the line 33 of Figure 1.

Figure 4 is an enlarged vertical sectional view on line 44 of Figure 3.

Figure 5 is a detached perspective view showing a portion of the ighter and that part which extends into the pipe connectmg the main burner and the oven burner.

In the several figures of the drawing, 1

indicates the open portion of a range and 2 the wall of an oven. This oven has any desired form of door 3, and in the range the even may be in the lower part as here shown or in the upper part, or the lower part 2 may be the broiler. Whether the broiler forms the lower or the upper portion of the housing 2, there is provided what I term an oven burner 3. This burner is sl 1own, suhstantially rectangular in plan view, having it manifold '4 extending in a direction crosswise of the range and its two parallel arms 5 extending parallel the range and its cross arm 6 extending parallel with the arm 4. The two parallel arms 5 are provided on the underside with suitable slits 6 which form burners. In the construct-ion here shown, the part 6 is detachably secured bynmeans of bolts 7 to brackets 8 that 70 extend out from the outer wall 9 of the oven housing.

Located in the open part 1 of the range is what I term a main burner 10. This main burner is fully shown and fully described in my pending application of which this is a continuation in part as hereinbefore stated, and an auxiliary burner 11 here shown in dotted lines connected by a pipe 12 with the main burner, is also shown and described. Therefore this main burner will not be more particularly described than is necessary to understand the present improvement.

The form of main burner here shown is adapted to use a hydrocarbon fuel, and the flow of the fuel to the burner is controlled by a suitable handle 13 in the same manner as in the said copending application. This burner also" has located under it an initial lighting construction 14, for initially heating the said burner in the manner also explained in the copending application and which will be understood by those skilled in this art.

The particular improvement here presented pertains to a lighter 15 that has one end 16' located adjacent the ignition lightin or heating device 14 and its opposite end 1 located adjacent the burner slits 6. It will be 100 observed that this lighter is located under a pipe 18 that serves to connect the oven burner 3 with the main burner 10.. The main burner 10 supplies sufiicient vapor that flows from'the main burner to the oven burner 4 105 and this vaporis controlled by a suitable valve rod 19. i In the present construction the lighter 15 has an upwardly extending communication 20 that enters an opening 21 formed in the 110 said pipe 18. This projection consists as shown, of a tube that extends into the pipe tention is called to a and the inner end of the tube next to the main burner is cut away as shown at 21 that forms a circular portion 22. Passing through this tubular portion 2 is a bolt 23 and the bolt passes through the upper portion of the pipe 18 and receives a suitable nut 24. Attention is directed to the fact that the lighter 15 has its ends 25 flattened, and the flattened ends are slightly open, forming a transverse slit 26 (Figure 5), and the ends of the lighter are provided with a longitudinal slit 17 that connects the slit 26 with the series of transverse extending slits 28 formed on the under side of the lighter. It will be understood, of course, that the vapor from the main burner entering the pipe 18, part of it is deflected by the circular portion 22 downward into the lighter 15 and the'vapor flows in both directions within the lighter, part of it flowing through the slits 26 and 27, adjacent the underside of the main burner and is lighted by the flame from the initial starting device and then the flame flashes back on the under side of the lighter to its end 27 and the flame adjacent to the slits 6, thereby lighting the said oven burner.

For the purpose of protecting the lighter flame, a suitable hood 29 extends below the lighter, thus embracin out thelighter. This is for the purpose of protecting the lighting flame from side drafts causing the lighter to be sure to operate in the manner intended. While this hood may be formed in other ways, in the form here shown, it has its upper ends 30 doubled around the top of the lighter and in that manner it is held. The lighter being intermediately pivoted to the under side of the pipe 18, has a tendency to swing, and for the purpose of holding the same in its proper position, I provide rods 31 which' depend from the underside of the pipe connection. In this manner the position of the lighter is insured so that when it is desired, the flame will be conveyed in the manner previously explained.

The main burner 10 has its housing divided into an upper small burner chamber 32 and a lower large ,vaporchamber 33 by means of a suitable division wall 34, the same as described in the said application. A suitable generator 35 provides the vapor for the lower vapor chamber 33, and the flow of vapor through the conduit or tube 18 is controlled by the said handle. 19 carrying a gear 36 that operates a valve 37 that is adapted to control the opening 38 between the conduit and the vapor chamber 33. At-

post 39, in Fig. 3, against which the valve 37 abuts in its inward position therebylimiting the inward movement of the valve, while its outer movement s limited by the Wall of the opening the flame through 38 against which the valve abuts when it is closed. It will be observed that the tubular portion 20 between the conduit 18 and the lighter 15 is located between the valve 37 and the point where the lighter commupicates with the said burner. Therefore when this valve 37 is closed, vapor cannot reach the said lighter, and it is only when the valve 37 is open to feed the vapor to the oven burner 3 that the vapor passes fromthe conduit to the lighter.

Other features of the parent case which may be herein shown are not described since they are clearly shown and described in the said application.

I desire it understood that the present improvement may be varied by those skilled in the art without departing from the invention so long as the said changes come within a fair interpretation of the appended claims.
